So what is the appropriate pattern here?  Change this function to return 
an error code, pass the actual result out as a reference parameter, and 
if arglist or isfiltered is NULL return a bad error code?  Then handle 
that in the caller?

I'd almost rather just allow the segfault and not ugly up the code with 
all that handling :/  c is so obtuse...
